Abstract

L'invention concerne un diffuseur conçu pour un système d'alimentation. Ce diffuseur peut comprendre une base disposée perpendiculairement à un écoulement, un corps s'étendant à partir de la base en direction de l'écoulement, et une pointe située à une extrémité du corps et orientée en direction de l'écoulement. Les dimensions du corps peuvent diminuer en section transversale de la base à la pointe.
